The invention relates to a high-salt wastewater treatment machine, in particular to a high-salt wastewater desalination union treatment machine adopting copper alloys and a mouse-cage type air cooling motor. The high-salt wastewater desalination union treatment machine comprises a clarification tank, a filtration tank, a sodium ion exchanger, a carbon remover, a three-level fine filter set and a union energy recovery reverse osmosis assembly. As improved, a pressure boosting union joint, a pressure relief union joint, a suction port union joint and a pressure storage union joint are arranged on a pressure exchange union booster pump; the pressure boosting union joint comprises a volute outlet union retainer ring, a high-pressure conversion union external thread and a volute union outer ring, a volute outlet sealing spherical surface is formed on the volute outlet union retainer ring, a high-pressure conversion sealing concaved conical surface is formed on the high-pressure conversion union external thread, and an outer ring step surface and an outer ring internal thread are formed on the volute union outer ring; two sides of a pump partition are matched with a pressure exchange union casing and a primary pump casing respectively; with the adoption of the union pipe connection structure, connection and mounting in a distorted narrow space can be realized; by the aid of the added pressure exchange union booster pump, the energy saving effect is remarkable. |
